Java Dependency Manager (jdeps) is recognized as the Java class dependency. It is deployed to assist the user with completely new APIs that is potential to replace the former one without hampering the functionality.
2. Java Statistics Aggregator (jstat)
Java Statistics Aggregator, in short, it is known as jstat. It is recognized as a utility tool for displaying the performance statistics of the Java Virtual Machine.
jstat command is exclusively used when the user is suffering from runtime problem.
3. Java Compiler (javac)
